.SH NAME
std::messages::close,std::messages::do_close \- std::messages::close,std::messages::do_close

.SH Synopsis
   Defined in header <locale>
   public:                                   \fB(1)\fP
   void close( catalog c ) const;
   protected:                                \fB(2)\fP
   virtual void do_close( catalog c ) const;

   1) Public member function, calls the protected virtual member function do_close of
   the most derived class.
   2) Releases the implementation-defined resources associated with an open catalog
   that is designated by the value c of type catalog (inherited from
   std::messages_base), which was obtained from open().

.SH Parameters

   c - a valid open catalog identifier, on which close() has not yet been called

.SH Return value

   \fI(none)\fP

.SH Notes

   On POSIX systems, this function call usually translates to a call to catclose(). In
   GNU libstdc++, which is implemented in terms of GNU gettext(), it does nothing.

.SH Example

   The following example demonstrated retrieval of messages: on a typical GNU/Linux
   system it reads from /usr/share/locale/de/LC_MESSAGES/sed.mo.


// Run this code

 #include <iostream>
 #include <locale>

 int main()
 {
     std::locale loc("de_DE.utf8");
     std::cout.imbue(loc);
     auto& facet = std::use_facet<std::messages<char>>(loc);
     auto cat = facet.open("sed", loc);
     if (cat < 0)
         std::cout << "Could not open german \\"sed\\" message catalog\\n";
     else
         std::cout << "\\"No match\\" in German: "
                   << facet.get(cat, 0, 0, "No match") << '\\n'
                   << "\\"Memory exhausted\\" in German: "
                   << facet.get(cat, 0, 0, "Memory exhausted") << '\\n';
     facet.close(cat);
 }

.SH Possible output:

 "No match" in German: Keine Übereinstimmung
 "Memory exhausted" in German: Speicher erschöpft
